Conventionally compressor (Compressor) is the power of accepting from power generation arrangements such as electric motor or turbo machines, the mechanical device that air, refrigeration agent or other multiple working gas is compressed to improve to pressure, is widely used in the electrical equipment such as refrigerator, air-conditioning or whole industry.
Such compressor is roughly divided into: reciprocal compressor (Reciprocating compressor), between piston (Piston) and cylinder (Cylinder), be formed with for sucking, discharge the compression volume of working gas, make piston carry out straight reciprocating motion in cylinder interior and carry out compressed refrigerant; Rotary compressor (Rotary compressor), is formed with for sucking, discharge the compression volume of working gas between the roller (Roller) of eccentric rotary and cylinder carrying out, and makes roller carry out eccentric rotary along cylinder inner wall and carrys out compressed refrigerant; Scroll compressor (Scroll compressor), between moving scrollwork (Orbiting scroll) and fixed scroll (Fixed scroll), be formed with for sucking, discharge the compression volume of working gas, make described moving scrollwork rotate compressed refrigerant along fixed scroll.
Recently, in described reciprocal compressor, a lot of following Linearkompressors have especially been developed, that is, piston is directly connected with the drive motor that carries out linear reciprocating motion, thus the mechanical loss not causing because of motion conversion, can improve the efficiency of compression, and there is simple structure.
Generally, Linearkompressor forms in such a way, that is, in the enclosure interior of sealing, piston carries out linear reciprocating motion by linear motor in cylinder interior, thereby suck refrigeration agent, compresses discharge afterwards.
In described linear motor, permanent magnet is between inner stator and external stator, and the mode that permanent magnet carries out straight reciprocating motion with the mutual electromagnetic body by between permanent magnet and interior (or outer) stator is driven.And along with described permanent magnet is driven with the state being connected with piston, piston carries out linear reciprocating motion in cylinder interior, thereby suck refrigeration agent, compress discharge afterwards.
Fig. 1 and Fig. 2 illustrate the structure of the magnet assembly 1 of Linearkompressor in the past.Described magnet assembly 1 comprises: magnet framework 2, and it is general cylindrical shape shape, and the driving force of linear motor is passed to piston; Permanent magnet 3, it is fixed on the outer circumferential face of described magnet framework 2.
